In this photo taken Thursday, April 4, 2013, Surgeon Dr. John Lipham holds a sample LINX device at the Hoag Memorial Hospital Presbyterian in Newport Beach, Calif. The LINX System is designed to help the esophageal sphincter stay closed to stop the reflux. It uses a small, flexible band of beads. Each bead has a magnet inside. When placed around the outside of the esophagus, the magnetic attraction between the beads helps the sphincter stay closed to prevent reflux. Swallowing food will overcome the magnetic attraction and allow the beads to separate, allowing food and liquid to pass normally into the stomach. (AP Photo/Damian Dovarganes)
